Definitions
- This invention relates generally to suspension ceiling grid systems, and more particularly to a novel and improved, narrow-faced grid for suspension ceilings which provides panel centering means to ensure that the panels are properly supported on the narrow panel supporting flanges of the grid.
- Grid systems for suspension ceilings typically provide inverted T-shaped grid members which are formed with a central web, a bulb at the upper extremity of the web, and oppositely extending panel supporting flanges at the lower edges of the web.
- the flange width of such grids are usually 15/16 inch to 1 inch in width.
- Such grid members or runners are interconnected to define rectangular panel openings bounded by the panel supporting flanges.
- the center-to-center distance between runners on opposite sides of each opening determines the module size of the grid opening.
- one common module size is 2' ⁇ 4'.
- the center-to-center spacing of the grid members extending along the long sides of the panel openings is 2 feet
- the center-to-center grid spacing of the grid members along the narrow side of the panel openings is 4 feet.
- the standard panels for installation in such a grid are rectangular, and are undersized in both directions 1/4 inch ⁇ 1/16 inch.
- the panels are produced undersized or with clearance so that they can be easily positioned in or removed from the grid panel openings. Such a clearance ensures that the panels can be dropped down past the grid bulbs and the grid hanger wires and so that the panels will not bind on the webs of the grid.
- the minimum dimension of a panel for a 2' ⁇ 4' module grid system is 1', 11 11/16 inches by 3', 11 11/16 inches. Since the standard grids have a flange width of at least 15/16 inch, the spacing between the web of a grid member from one side of a panel opening at the closest edge of the panel supporting flange on the opposite side of the opening (assuming a 2' ⁇ 4' module) is 1', 11 17/32 inches by 3' 11 17/32 inches.
- the webs are assumed to have zero thickness because they generally are formed of thin metal.
- a non-centered panel (a panel positioned along one or two edges against the adjacent web) still extends over the opposed flange and is supported thereby by more than 1/8 inch. Because webs actually have some thickness, the overlap in the case of the non-centered panel is greater than 5/32 inch, and is usually at least about 3/16 inch, even when the panels are at minimum dimensions of their tolerances and are offset from the center the maximum possible amount.
- FIG. 8 illustrates a typical prior art grid system in which the grid members provide a face or flange width of 15/16 inch and a standard lay-in panel with 5/16 inch clearance is positioned in a maximum off-center position but is still properly supported.
- Such grid has a shape or cross section substantially as illustrated in U.S. Pat. No. 4,021,986.
- Such grids have been produced with a face width of about 9/16 inch, and are used with panels which are rabbeted along their lower edges to fit down along the sides of the lower box sections.
- Such panels when installed, provide lower faces which are flush with the lower edges of the box section, as illustrated in FIG. 2 of such patent.
- the engagement between the vertical sides of the rabbets and the sidewalls of the box section operates to center the panels within the openings, and thereby assure adequate panel support along all sides thereof, even though the panel supporting flanges at the upper edges of the box section are relatively narrow.
- the present invention provides a novel and improved, narrow-faced grid system which can be used with conventional lay-in panels, and does not require the use of rabbeted panels.
- Such grids provide substantially conventional T-shaped grid members which provide a central web, a bulb along one web extremity, and opposed panel supporting flanges along the opposite web extremity. Such flanges, however, are narrower than conventional grids.
- the flanges are preferably at least about 9/16 inch wide when used with standard clearance panels, and are therefore incapable of reliably providing full support of non-centered panels.
- centering means are combined with the grid members which operate to center the panels and ensure proper panel support, even though the flanges are relatively narrow.
- the grid web is formed with laterally extending tabs which are shaped and sized to cam the panels to a center position and to maintain them in such position.
- spring clips are located at intervals along the grid, which resiliently maintain the panels in their centered position.
- a simple, low-cost suspension ceiling grid system in which the grid members are formed with aesthetically desirable, narrowface. Because the grid face is narrow compared to conventional wide-faced grids, narrower material may be used to produce the grid members than is required to produce conventional wide-faced grid. Further, such grid members may be used with standard unrabbeted lay-in panels or tile.

- FIG. 6 is a fragmentary side elevation of the embodiment of FIG. 5;
- FIG. 7 is a fragmentray broken view of an installed ceiling, similar to FIG. 4 but illustrating such ceiling with grid members in accordance with the second embodiment of FIGS. 5 and 6;
- FIG. 8 is a fragmentary cross section of a typical prior art wide-faced grid illustrating how even off-center panels are supported.
- FIGS. 1 through 4 illustrate a first embodiment of this invention, in which grid members are provided with integral centering means at spaced locations along the webs of the tees.
- FIG. 3 illustrates the cross-sectional shape of the tee.
- tee 8 is symmetrical about a central plane 9 and includes a central web 10 providing a bulb 11 at the upper extremity of the web and opposed, laterally extending flanges 12 at the lower extremity of the web.
- the tee is formed of a strip of material which extends inwardly from one edge at 13 to a first right angle bend at 14. From the right angle bend at 14, the strip extends up providing one layer 16 of the web at 10. At the upper extremity of the web layer 16, the strip is bent outwardly at 17 and above the web is formed in a closed box shape to provide the bulb 11. The strip then extends down the second web layer 18 to a right angle bend at 19 and out along the flange 12 to an edge 21.
- a cap strip 22 is folded over the two outer edges 13 and 21 to form the face portion of the flanges.
- the tee section thus far described is conventional in that it provides a bulb at one extremity of the web, a double-faced web and oppositely extending flanges at the lower extremity of the web.
- the flanges 12 are much narrower than provided in a conventional grid tee and have a total face width of about 9/16 inch.
- conventional grid tees usually have a face width or flange width of 15/16 inch or 1 inch.
- a plurality of centering tabs 26 are Formed at intervals along the length of the web. These tabs in this illustrated embodiment are formed by making a U-shaped cut 27 through the two layers 16 and 18 of the web 10. Such cut produces a downwardly extending tab 28 which is twisted, as best illustrated in FIG. 3, to provide a first portion 29 substantially parallel to the plane 9 of the grid tee 8 and laterally spaced therefrom on one side of the web and a second portion 31 substantially parallel to the plane 9 but laterally spaced therefrom on the opposite side thereof. Intermediate the two portions 29 and 31, the tab provides an inclined or laterally extending portion 32 which joins the two portions 29 and 31.
- the two portions 29 and 31 are essentially planar, and in the illustrated embodiment are displaced on opposite sides of the central plane of the web 10 so that the outer surfaces of the portions 29 and 31 are spaced apart almost a quarter of an inch, with the result that such surfaces are located at slightly less than 1/8 inch on each side of the central plane 9 of the web 10.
- the tab provides two camming portions or transition portions 33 and 34, which are inclined inwardly from the planar portions 29 and 31, respectively, into the web itself.
- the planar portions 29 and 31 are spaced upwardly from the flanges 12 a short distance, and are sufficiently close to the flanges so that when a conventional tile or panel is placed in the grid opening, the planar portions engage the edges of the panel and space the edges thereof from the plane 9 of the web by a distance about 1/8 inch.
- the centering tabs 26 are formed in the web at intervals along the length of each of the grid tee members, e.g., at intervals of about 3 inches.
- a pair of grid tees 8 are located on opposite sides of each opening and the spacing between the central planes 9 is determined by the module size.
- One typical module size is 2' ⁇ 4'. However, other module sizes are commonly provided.
- the panel openings are defined by opposed pairs of grid tees 8, with the first pair defining the 2-foot module dimension and perpendicularly extending second pairs defining the 4-foot module dimension. As illustrated in FIG. 4, one of the module dimensions is defined by a pair of parallel and laterally spaced grid tees 8a and 8b and an adjacent opening defined by grid tees 8b and 8c.
- the central planes 9a are spaced apart, for example, by 2 feet or 4 feet, depending upon which pair of grid members are being considered. For purposes of discussion, it is assumed that the grid members 8a and 8b define the 4-foot dimension of the module. Therefore, the central planes 9a of these two grid members are spaced apart 4 feet.
- the adjacent edges 36 and 37, respectively, of the grid members 8a and 8b are spaced apart by a distance of 4 feet minus 9/16 inch, or 3 feet, 11 7/16 inches.
- the spacing between the planar portion 29 of the centering tab on the grid 8a and the planar portion 31 on the centering tab of the grid member 8b is slightly more than 3 feet, 11 3/4 inches.
- a standard panel is provided with a clearance of 1/4 inch ⁇ 1/16 inch, so a minimum corresponding dimension of a conventional 2 ⁇ 4 panel is 3 feet, 11 11/16 inches by 1 foot, 11 11/16 inches, and a maximum panel size within the tolerance range would be 3 feet, 11 13/16 inches by 1 foot, 11 13/16 inch.
- Even a minimum size panel therefore, provides a lateral width along the 4-foot nominal dimension, which is greater than the lateral spacing between the adjacent edges of the adjacent flanges of 3 feet. 11 7/16 inch by about 1/4 inch. Therefore, when a panel 38 is dropped into the opening and is centered by the centering tabs, it is supported or overlays the associated flange by about 1/8 inch along each side edge of the panel. If the panel having a maximum dimension of 3 feet, 11 13/16 inches is inserted in the opening, it provides slightly more overlap or support by the flanges.
- the centering tabs are sufficiently resilient to be deflected a small amount when a maximum diameter panel is installed to prevent binding or, in some instances in which the panels themselves are formed of relatively soft material, the centering tabs may provide a slight indentation of the concealed edges of the panels.
- a grid formed of grid members incorporating the first embodiment are provided with relatively narrow faces in the order of 9/16 inch wide, and proper support of standard panels is achieved because of the centering mechanism provided at intervals along the length of the flanges.
- the face width of the grid tees is about 9/16 inch, which is less than twice the maximum panel clearance, and yet reliable panel support is provided.
- each of the planar portions of the centering tabs 29 and 31 is joined to the adjacent portions of the web immediately thereabove by an inclined camming surface 33 or 34, the panels do not hang up and are automatically centered as they drop into position in the grid openings.
- FIGS. 5 through 7 illustrate another embodiment of this invention which provides a narrow-faced grid member in combination with centering means which ensure proper panel support with conventional lay-in panels.
- the grid member 51 provides a central web 52 formed with a closed, generally rectangular bulb 53 at its upper extremity and a pair of laterally extending flanges 54 at its lower extremity.
- the web 52 provides two layers 56 and 57, and the grid is symmetrical with respect to the central plane 58.
- a cap strip 69 extends along the lower faces of the flanges 54 and is bent around the outer edges thereof.
- the cross section of the grid is identical with the cross section of the grid of the first embodiment. However, other cross sections may be utilized.
- a spring clip 61 is mounted on the grid 51 at intervals along the length of the grid.
- Such spring clip is preferably formed of a thin, relatively resilient metal, and provides a U-shaped bend 62 at its upper end. Extending downwardly from the bend 62 are laterally spaced leg portions 63 and 64 which engage opposite sides of the bulb 53 and continue down along the opposite sides of the web 52. At the lower ends of the legs 63 and 64, the clip is provided with arcuate, outwardly extending end portions 66 and 67, respectively.
- the legs are provided with inturned tabs 68 which extend in under the underside of the bulb 53 to prevent vertical upward movement of the clip with respect to the grid.
- tabs are shaped to blend into the legs as they extend downwardly so that the clip may be easily installed on the grid by simply pressing the clip down over the bulb. As the tabs pass the bulb, they cam the legs apart until the clip is properly installed and the tabs snap in underneath the bulb to lock the clip on the grid tee.
- the grid tees are formed with a flange or face width of about 9/16 inch when intended for use with conventional panels.
- the lower extremities of the portions 66 and 67 are substantially in vertical alignment with the adjacent edges of the flange.
- the legs are deflected inwardly from their unstressed condition by the engagement with the edges of the panels, as best illustrated in FIG. 7, and cooperate with the clips on the next adjacent parallel grid tee to automatically center the panels with respect to the panel openings.
- the edges 72 thereof engage the arcuate end portions 66 and 67, causing the legs to be deflected from their unstressed conditions inwardly. Because these portions are arcuate, a smooth camming action is provided.
- the legs are deflected from their unstressed condition and the legs engaging the opposite edges 72 of the panel automatically operate to center the panel with respect to the grid, so that the edges are spaced from the central planes 58 of the grids an equal amount around the entire panel opening. It is preferable to form the arcuate end portions 66 and 67 so that their lower edges 73 are spaced from the edges 72 of the panels when the panels are installed so that they do not dig into the panels if and when it becomes necessary to remove the panels from the grid.
- a centered panel is supported by at least about 1/8 inch overlap around the entire periphery of the panel. This condition exists even though the flanges have insufficient width to properly support a non-centered panel.
- the use of a separate centering clip simplifies the manufacture of the grid members.
- the only change in the grid member from conventional prior art grid members is the provision of a narrow face width. Therefore, production costs of the grid members are not increased and, since the grid face is narrower than conventional grids, material savings are achieved in the manufacture of the grid.
- the clips need only be provided at intervals along the length of the grid, they do not materially increase the material costs or manufacturing costs of the assembled grids.
